Gelbke built the Roadogs using existing technologies
in ways no one else had. They took form with a frame built from aircraft
tubing. The powertrain and engine were the same used in the Chevy II Nova. The
rear end of the bikes were modified one-ton Chevy truck differential.

Other elements of Roadogs design were unique to
the motorcycle world. They had twin headlights and were the first motorcycles with
an automatic transmission. The bikes had disc brakes from a Corvette and was
equipped with four hydraulic stands to keep it upright when parked.
